Application filed 1' une 13, 1916. Serial No. 108,531.

To all whom z't may concern.' j

Be it known that I, THEoDoRE Romans, a citizen of the United States,residin at Poplar, in the county of Sheridan and tate of Montana, haveinvented new and useful Improvements in Gil-Cans, of which the followingis a specification.

This invention relates to oil cans of the forced feed type, and one ofthe objects of the invention is to provide means whereby the oil may beejected from the can when the said can is sustained either in a verticalposition, at an inclination or when the said can is inverted.

1n carrying out my invention I propose to construct an oil can whereinthe handle provides the cylinder for the air pump and to arrange withinthe said can an auxiliary reservoir providing what may be termed acompression chamber receiving the air from the pump and having a port orports communicating with the interior of the can proper, an outlet tubebeing arranged within the can and communicating with the 21S chamber, avalve spout being provided for the tube, the valve having a single portand which is normally retained in a closed position by spring pressedmeans having an operative member disposed in close proximity at to thehandle, whereby the same may be easily actuated by the operator and alsowhereby a certain quantity of the oil will at all times be retained inthe compression chamber regardless of the angle at which the can isheld, tu so that even when the can is inverted oil may be dispensedtherefro It is a further object of the invention to produce a device ofthis character which shall embody the desirable features of simauplicity, cheapness and thorough eciency.

With the above and other objects in view the improvement resides in theconstruction, combination and arrangement of parts set forth in thefollowing specification and fall- 415 in within the scope of theappended claim.

n the drawing:

Figure 1 is a side elevation of an oil can constructed in accordancewith the present invention,

Fig. 2 is a central vertical longitudinal sectional view through thesame,

Fig. 3 is a horizontal sectional view through the device taken in aplane above the compression chamber.

Fig. 4 is an enlarged detail sectional view approximately on the line1-41 of Fig. 2,

Fig. 5 is an enlarged sectional view through the valve showing the samein its closed position, and

lig. 6 is a similar view showing the valve in lts open position. A 1nthe drawing like reference characters designate corresponding partsthroughout the several views, and the numeral 10 designates the can bodythat has its top provided with a filling opening closed by a removablecap 11,

The handle is indicated b the numeral 12 and comprises a c lindricaiImember within which is arrange a piston operated by a suitable rod 13that rojects through the upper and open end o the tube 12. rlhe tube, atthe upper end thereof, is connected to the can 10 by a bracket 14: andto the lower end of the said can by a pipe member 15 which provides theair inlet port for the can.

Arranged in the can, adjacent the bottom thereof is the compressionchamber, indicated by the numeral 16. The com ression chamber includes atop 17 which is isposed angularly with relation to the straight bottomof the can, the said top portion 17 slanting from a suitable distanceabove the air inlet port 15 toward the opposite side and bottom of thecan 10, and the top 17 of the compression chamberis provided with anangular side 18 which is connected with the bottom of the can but which,for the major portion thereof, is spaced away from the sides of the canso as to provide a passage for the oil in the can between the said canand the compression chamber 16. The numeral 19 designates the oilinletportion which, it will be noted, is disposed below the air inlet portion15, the pipe providing the said ihlet port communicating with thecompression chamber 16. The sides of the compression chamber may beprovided wlth one or more restricted apertures in the nature of bleedports 20, whereby the air com pressed within the chamber 16 may find anexit to within the can 10.

The numeral 21 designates the outlet tube arranged between thecompression chamber and top of the can 10, the said tube being disposedpreferably diametrically opposite the handle 12, and the end thereof,extendl` ing through the top of the can, is provided with a valve casing22 in which is arranged a valve 23 having a single port 24, andconnected with this valve isa stem 25 which passes transversely over thetop of the can ejected through the and has its free end supported by abracket 26. The end of the rod 25 extending beyond the bracket 26 hasarranged thereon a han dle 27 provided with an offset finger 28 that isadapted toxcontact with the stoplug 29 upon the bracket 26 and thenumeral 30 designates a l spring which surrounds the stem 25- and hasone of its ends secured to the bracket 26 and its opposite end securedto the stem whereb the valve 23 may be normally turned to ring the port24 thereof transverse of the port in the valve casing and normally closethe tube 21. The numeral 31 designates the outlet spout connected withthe valve casing 22.

The operation of the device may be briefly described as follows:Suflicient oil will be allowed to pass through the port 19 from the can10 to the compression chamber 16 and when the piston in the hollowhandle is actuated to force a desired amount of air to within thecompression chamber oil will be tube 21, port 24 of the valve 23 andthrough the outlet spout 32, when the operating member 27 is actuated tobring the port 24. into alinement with the ports or bores of the tube ofthe spout.

vWhen pressure upon the handle 27 is released, the spring 30 will, asstated, turn the valve toits operative position. By constructing thecompression chamber w1th an angular top, it will be noted that even whenthe can is completely reversed, a sufficient quantity of oil will bemaintained within the compression chamber to properly lubricate theparts of the machine when the valve is actuated.

From the above description, taken in connection with the accompanyingdrawing, the simplicity of the device, as well as the advantages thereofwill, it is thought, be perectly apparent to those skilled in the art towhich such invention appertains without further detailed description.

Having thus described the invention, what l claim is: The hereindescribed forced feed oil can, includin a body having its handle in thenature o an air pump, a compression chamber within the body at thebottom thereof,

said chamber having an upper inclined wall which is round in plan, aflange secured to the periphery of the said wall and connected to thebottom of the receptacle and spaced from the sides of the saidreceptacle at all points except at thev reduced endof the chamber, saidchamber having an entrance opening in a line with the bottom wa'll ofthe receptacle and having a pipe communication with the pump adjacentthetop of the chamber at the widened end thereof, said chamber, belowthe said pipe connection having bleed openings, and an outlet spoutbetween the reduced end of the said chamber and the top of the can.

In testimony whereof I ailix my signature.
